Alan Stern posted a patch that could potentially solve the problem to linux usb mailing list.
http://thread.gmane.org/gmane.linux.usb.general/45577/focus=45587 I modified that patch to be able to apply it to Ubuntu Natty linux kernel 2.6.38. Patched kernel was then compiled on Lucid. I started to run tests with 2.6.38 kernel on Lucid today. ** Patch added: "usb-ehci-fix-lucid-2.6.38-10.patch" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/349767/+attachment/2151796/+files/usb-ehci-fix-lucid-2.6.38-10.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/349767 Title: external USB hard drive disconnects -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
